Red Notification light then reboot

[skycamefalling]

Hi guys,

I have the Xperia Z5 compact for 3 days now. Today I was reading an email as suddenly the notification light started blinking red and the phone crashed to immediately start anew.

Now it's fine again but I feel a bit uneasy as I never encountered something like this on any Xperia before...what was it? Will it happen again? Is it a hardware issue so that I should exchange the phone?

Hoping to get some opinions here or maybe some experiences from you guys

Thanks.

So the phone restarted? It might have been a system crash caused by some app. Keep an eye on it for now and report if that will happen again.

Hello skycamefalling,

I too suffered from this issue for a while. The red light notification reboot took place randomly 5 times in a span of maybe two weeks, then, it stopped without any special acting from me. It hasnt occured for three months now. Make sure you have latest software installed.

Thanks guys,

yes, the latest firmware .200 is installed.

I'm not using many apps and only very few of them are doing something in the background.

So if it was a system crash if could be the email-app itself of maybe Garmin Connect which was syncing with my Fenix Watch in the background via Bluetooth.

I'm used to Android's system crashes, however what bugs me is the red notification light. I've never seen it before and it looks dangerous

Who knows...will keep an eye on it during the next days. I just don't want to miss my 14days-return-possibility in case it's a hardware fault.

Keep us updated.

Had the same reboot issue again. This time the phone did not restart but I had to restart it manually.

I was out for a walk when suddenly my smartphone reported a lost Bluetooth connection to the phone. I took the Z5c out of my pocket and saw that it was off. It wouldn't reboot for one minute, only showed the red notification light.

Then, suddenly, it started again.

I've been having this issue from time to time as well.. Haven't figured out what causes it yet but mine 'mainly' does it when I ask a bit too much of it (in its opinion, not mine ;))

Got my z5c on launch day. Been happening ever since. Factory reset doesn't fix. It stopped briefly but now it's back 2/3 times a day.

Just trying to arrange sending it back to Sony under warranty.

I'm guessing they'll just do basically the same thing and return it as fixed though. Then in a weeks time it'll return

Same issue here, had it since I bought the phone, online it seems its quite common, I wish Sony would acknowledge it and provide a fix, as the factory reset didnt fix it.
